Budget and Enrollment Forecast
10.3.1 - Budget and Enrollment Forecast
(Rev. 30, 09-05-03)
The HCPPs must submit an annual operating budget and enrollment forecast at least 60
days before the start of each reporting period. The operating budget uses estimated costs.
The budget and enrollment forecast must reflect the HCPP's past experience and present
the HCPP's anticipated enrollment and costs (both total and Medicare) for the coming
reporting period. The reports are then used to compute the interim per capita rate. Its
other purpose is to establish Medicare deductible and coinsurance premiums, including
determining past over or under collections of such premiums and the budget period's
voluntary under collection of premium. If the budget and enrollment forecast is not
submitted on a timely basis, CMS may:
• Establish an interim per capita rate of payment on the basis of the best available
data and adjust payments based on such a rate until such time as the required
reports are submitted and the new interim per capita rate can be established, or
• Advise the HCPP if there is not enough data on which to base an interim rate,
then interim payments will not be made until the required reports are submitted.
The CMS reserves the right to examine all records and statistical data used by the HCPP
in completing these reports. To the extent the annual operating budget and enrollment
forecast is accurate, interim payments will approximate the total CMS obligation.
